PROGRAMMING ALGORITHMS
The PIC16F193X/PIC16LF193X devices have the
capability of storing eight 14-bit words in its data
latches.
The
data
latches
are
internal
to
the
PIC16F193X/PIC16LF193X devices and are only used
for programming. The data latches allow the user to
program up to eight program words with a single Begin
Externally Timed Programming or Begin Internally
Timed Programming command. The Load Program
Data or the Load Configuration command is used to
load a single data latch. The data latch will hold the
data until the Begin Externally Timed Programming or
Begin Internally Timed Programming command is
given.
The data latches are aligned with the 3 LSb of the
address. The address at the time the Begin Externally
Timed Programming or Begin Internally Timed Pro-
gramming command is given will determine which loca-
tion(s) in memory are written. Writes can not cross a
physical eight-word boundary. For example, attempting
to write from address 0002h-0009h will result in data
being written to 0008h-000Fh.
If more than 8 data latches are written without a Begin
Externally Timed Programming or Begin Internally
Timed Programming command the data in the data
latches will be overwritten. The following figures show
the recommended flowcharts for programming.
